m1; :WWm-M AHMAD +0 9 o'znnnfl nnnhm misses a substantiallv straight tubular sec- For this latter purpose, the peripheral wall of the tubular section 1 is proided with a plurality of radial slots or openings 20 alined with the corresponding flukes lto serve as guides through which the flukes may fold and unfold as the rod 14 is moved endwise in reverse directions.

That is, the end walls of the slots or openings constitute abutments against which the outer ends of the corresponding flukes are adapted to engage and by which they are deflected outwardly or inwardly according to the direction of movement of the rod 1 l-.

These fiukes 15 are pivoted to the rod c1t at different levels so that each moves about a separate axis, some of the pivots be ing disposed at right angles to others so that the flukes may fold and unfold in diiferent planes; it being understood that the openings will be arranged at different levels corresponding to the position of their respective flukes.

It will be observed that the lengths of the 7 several flukes are substantially the same and is considerably greater than the radius of the tubular section 1 so that when unfolded to the position shown by dotted lines in Figure 1 they will project some distance beyond the periphery of the tubular section for engagement with the ground.

The upper end of the rod 14 is provided with an eye -21 adapted to be en gaged by the hook "13- on the lower end of the screw -9 whereby the upward adjustment. of'the screw 9 will cause a corresponding upward movement of the rod 1.l thereby bringing the outer ends of the flukes 15 into sliding engagement with the upper end walls of their respective slots 20 for unfolding the flukes through said openings and under the adjacent portion of the ground for firmly anchoring the tube against outward displacement from the ground after being driven thereinto.

This upward movement of the rod 14 may be continued until the shoulder 19- on its lower end engages the underside of the partition 18 at which time further upward movement will be checked and the flukes 15 will have been unfolded to a substantially horizontal position as shown by dotted lines in Figure 1, the unfolding movement of the flukes being further limited by the engagement of their lower fiat sides with the lower end walls of the slots 17.

As the screw 9 is unscrewed or turned in a direction to effect the upward move ment of the rod l4rand resultant unfolding of the flukes 15 it will exert a downward pressure upon the cap 3 and upon the upper end of the tubular section 1 to hold the sections l and 3- in operative engagement, with the pins 6 in the slots 5 which hold said sections against relative rotation while the resistance of the tubular section 1 in the ground prevents turning of both sections during the turning movement of the screw 9 it being understood that the engagement of the flukes 15 in the slots 20 holds the rod 14 against turning move ment when the screw 9 is rotated.

l/Vhen preparing the device for driving the tube 1 with the rod 14 and flukes 15 therein into the ground, if the cap section 3 is in operative position on the upper end of the tube and the hook 13 is engaged with the eye 21 on the upper end of the rod, the screw 9 will first be screwed downwardly thereby forcing the rod 14: to the limit f its downward movement and withdrawing the flukes l5- inwardly beyond the periphery of the tube 1 and if this turning movement of the screw 9 is continued the cap section 3 will be withdrawn from the upper end of the tubular section 1 until the hook 13- and eye -2l are exposed below the lower end of the cap section 3 as shownlin Figure 5 whereupon the cap section 3 with the screw 9 and hook -13- may be tilted laterally and the hook 13 disengaged from the eye 21-.

The cap section -8 with the screw 9 and hook 13- thereon is then re placed upon the upper end of the tubular section 1 with its pins 6 in the slots -5 at which time the hook 13 and eye -l2 of the screw 9 will be disposed at one side of the eye 21- and its rod 14 so as to extend downwardly some distance beyond the upper end of the eye 21.

Then the screw 9 will be screwed downwardly until its head 10 engages the upper end of the cap section 3 at which time the hook 13 and screw 9 will befree from connection with the rod 14 Now, by placing the tubular section 1 man upright position with its point at the location desired a sledge hammer or other pressure device may be applied to the upper surface of the head 10 which is then resting against the upper end of the .cap section 3- for driving the entire device into the ground to the required depth or until the flukes 15 are a sufficient distance below the surface of the ground to effect the desired anchoragev of the tubular section -1 therein when the fiukes are unfolded in the manner scribed.

That is, when the tubular section -1 with the rod 14' and flukes 15- therein previously deare driven to the required depth into the ground the cap section 3 which is then disconnected from the rod -1lr may be removed from the upper end of the tubular section -1 and the hook -13- re-engaged with the eye 21.

After the hook 13 is re-engaged with the eye -21- the cap section 3 is brought into vertical alineinent with the tu- 1 I '1 Ami] -C.M1w Ln li] 1 Ann moved from the upper end of the tubular section '1- a guy Wire or cable may be connected to the eye 21 and to the upper portion of a telegraph pole or other device which it is desired to hold in a more or less vertical position thus completing the installation of the ground anchor.
